CALL-BELL.

SPECIFICATION forming part of Letters Patent No. 247,610, dated September 27, 1881.

Application filed August 13, 1881. (No model.)

To all whom it may concern: y

Be it known that I, JOHN W. BUTLER, ot' New Britain, in the county of Hartford and State of Connecticut, haveinvented a new Improvement in Call-Bells; and I do hereby de- Clare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot' the-same, and

1o which said drawings constitute part otl this specification, and represent, in-

Figure l, a sectional side View; Fig. 2, perspective view of the hammer-holder detached; Fig. 3, perspectiveview ofthe hammer; Figs.

4 and 5, lnoditications. r

This invention relates to an improvement in that class ot' call-bells commonlyealled pressure-bellsthat is to say, such as have the bell hung upon a post with the spindle down zo through the bell, in connection with the hammer withinthe bell, so that pressing down the spindle will force-the hammer to strike the bell; then, when released, the hammer falling raises the spindle. In the usual construction the hammer is hung between two ears on the post, the ears and the shank of the hammer drilled to receive a wire pivot.

The object of this invention is to avoid the drilling of the ears and insertion of the pivot,

3o whereby the difficulty above referred to is pre- 4vented; and it consistsin constructing the post with an open Ybearing or seat which will receive a corresponding part of the hammer and support the hammer entirely without the in- 3 5 terposition of the usual wire pivot, as more fully hereinafter described.

A represents the base, and B the post which rises within the bell C, and on which the bell rests, and there secured by thetip D, extending 4o through an opening in the bell and screwed into the post, as shown in Fig. 1, and in the usual manner.

The post- B is constructedv with two hookshaped projections, a a, corresponding in position substantially to the usual ears, the mouth or open side of the hook upward toward the bell.

The hammer-shank E is constructed with the usual arm, F, upon which the spindle Gr structed to set upon the open bearings a a, the shank hanging between the said bearings, the bearings forming seats for the trunnions, and

on lwhich the hammer will freely swing'. The 55 hammer is hung in its position before the bell is set upon the post; then when the bell is in place it covers the open bearings, so as to preventthe possibilityot'dsplacementof the hammer.

Instead ot' forming the open bearing hookshaped'and trunnions b b on the hammer, the projecting arms may be connected by a bar, d; (see Figs. 4 and 5,) and the hammer, instead of the trunnions, is made with a hook shape, as at e, this being simply the reverse ot' the construction irst described, and so that the hamlner is hung by the hook c upon the bar d, ns seen in Fig. 4, and from which it cannot be removed after the bell is in place, because the 7o hammer cannot be raised sufficiently high to do so without coming in contact with the bell.

While I prefer the first-described construction, it will be readily seen that the reverse, as shown in Figs. 4 and 5, is an equivalent 75 therefor. In either case there is the same open seat or bearing and corresponding part to rest l thereon, so that the usual drilling and pivot will be avoided.

While the bell itseltl is all that is required 8o to hold the tongue in its seat-that is to say, will prevent its detachment therefromthe endsof the hooked-shaped projections a a may be bent over the trunnions b b, or,which is the same thing, the hook of the hammer bent over the bar, which would secure the hammer in place independent ot' the bell; but in that case it would be the open bearing on the post and corresponding part of the hammer, to rest thereon, which constitutes the essential feature 9o ot' my invention.

I claim- In that class of call-bells known as pressnre-bells,77 the post constructed with an open bearing, and the hammer constructed with a corresponding part, to rest on said open seat, substantially as described.

JOHN W. BUTLER.
